The most important thing regardless of brand is to try the gloves on. Take your wraps with you and wrap one hand. Then try the gloves. The shape and size inside gloves varies enormously from brand to brand and buying them off Ebay may end in disappointment.

I've got the Lonsdale authentic sparring gloves and bag gloves and they are a good glove for the money. The sparring gloves feel really snug and balanced, but it depends on your hands. I have long bony fingers and they just rattle around inside some gloves. My gym mate swears by Rival, but the fit just isn't right for me. The cheap vinyl Lonsdales are nasty though. They last all of two minutes and slice people up when sparring.

I got some really cheap at Sports World but they didn't last long. Some of the stitching started coming apart after a couple of months. Not that you'd expect them to last long on the hands of a devastating puncher like me
